The .280 Remington, a cartridge often overlooked in favor of its more popular cousins, offers a compelling blend of accuracy, flat trajectory, and manageable recoil. Understanding its ballistics is key to unlocking its full potential, whether for hunting or target shooting. This guide provides a detailed look at .280 Remington ballistics, examining various factors that influence its performance.
Understanding Ballistic Factors Affecting the .280 Remington
Before diving into specific charts, it's crucial to grasp the key factors influencing .280 Remington ballistics. These include:
-
Bullet Weight: Heavier bullets generally have lower velocities but greater energy and momentum at longer ranges. Lighter bullets offer higher velocities and flatter trajectories at shorter ranges.
-
Bullet Construction: The bullet's design (e.g., full metal jacket, soft point, hollow point) significantly impacts its ballistic coefficient (BC) and terminal performance. A higher BC means less drag and a flatter trajectory.
-
Powder Charge: The amount of powder used directly affects muzzle velocity and, consequently, the overall trajectory. Different powder types can also influence performance.
-
Barrel Length: A longer barrel generally results in higher muzzle velocities due to increased propellant burn time.
-
Altitude and Temperature: These environmental factors can influence air density, affecting bullet drag and overall trajectory.
Sample Ballistics Chart for the .280 Remington
While specific data will vary based on the factors mentioned above, the following table provides a general representation of the .280 Remington ballistics for a common 140-grain bullet with a relatively high ballistic coefficient, fired from a 24-inch barrel. Remember, this is not an exhaustive chart and should not be considered definitive. Always consult the manufacturer's data for the specific ammunition you are using.
| Distance (yards) | Velocity (fps) | Energy (ft-lbs) | Drop (inches) | Wind Drift (10 mph crosswind, inches) |
|---|---|---|---|---|
| 0 (Muzzle) | 2700 | 2800 | 0 | 0 |
| 100 | 2450 | 2200 | -2 | 6 |
| 200 | 2200 | 1700 | -9 | 15 |
| 300 | 1950 | 1300 | -22 | 27 |
| 400 | 1700 | 1000 | -40 | 42 |
| 500 | 1450 | 700 | -65 | 60 |
Note: Wind drift values are estimates and will vary depending on bullet shape and ballistic coefficient.
Finding More Specific Ballistics Data
To obtain the most accurate ballistic data for your specific .280 Remington ammunition and firearm setup, consult several resources:
- Ammunition Manufacturer's Data: Check the box or website of the manufacturer for their published ballistic information.
- Ballistic Calculators: Numerous online ballistic calculators allow you to input specifics about your ammunition, firearm, and environmental conditions to generate precise trajectory data. Several reputable brands such as Hornady, Sierra, and Berger offer these calculators on their websites.
- Chronograph: Using a chronograph will give you precise muzzle velocity data, which is crucial for accurate ballistic calculations.
Conclusion
Understanding .280 Remington ballistics is crucial for optimal performance. While this guide provides a general overview, remember that precise data is essential for accurate shot placement, especially at longer ranges. Consult the resources mentioned above to obtain the most accurate ballistic information for your specific setup. Always practice safe firearm handling techniques and follow all applicable laws and regulations.
